Dungeon Journal Description

The design of every Legion war machine stems from the depraved mind of Kin'garoth. Obsessed with crafting implements of death, Kin'garoth infused his very body into the production machinery so he could more efficiently churn out a never-ending supply of destruction. At the behest of the Legion's dark master, Kin'garoth's fevered brilliance has developed a new super-weapon which he plans to unleash upon the Army of the Light.
